Fish shell support

[unbalancedparentheses]

I am a http://fishshell.com/ user. The shell is awesome but it is on purpose not 100% POSIX compliant. I would be glad to add code to https://github.com/boot2docker/boot2docker-cli/blob/master/cmds.go#L194-L204 so that it prints how to export the variables in fish.

The equivalent of

export DOCKER_HOST=tcp://192.168.59.103:2376
export DOCKER_CERT_PATH=/Users/unbalancedparentheses/.boot2docker/certs/boot2docker-vm
export DOCKER_TLS_VERIFY=1

In fish would be

set -x DOCKER_HOST=tcp://192.168.59.103:2376
set -x DOCKER_CERT_PATH=/Users/unbalancedparentheses/.boot2docker/certs/boot2docker-vm
set -x DOCKER_TLS_VERIFY=1

I could also detect if the user is using fish with basename $SHELL and print the correct way to export the variables.

Let me know what you think so that I code it.

Thanks in advance!

Indeed! See #295, where @douglascamata has rebased someone else's PR to do exactly this.

See also the discussion on boot2docker/boot2docker#585 where we're talking about changing that to export everything regardless of what's set (since that'd be even simpler logic still).

Just adding myself here.

time to close this now.

Sorry, this repository is long-since deprecated in favor of Docker Toolbox (whose usage is now also discouraged in favor of Docker for Windows and Docker for Mac).
